About this 3D model

I got bored on a train ride and improved this old design. It's a replacement-part for the 4 bed holders and now should in theory reduce wobble in not only in 1 but 2 dimensions. It's an experiment and not yet proven to work well. (work in progress. I hope to get around to trying it when I take the machine apart anyway to replace all corners and the 4 Z-rods.)
